Introduction
The AKO Sun Power S 250 is a highly efficient, compact solar fence energizer designed for reliable operation in various agricultural settings. This device is ideal for managing paddocks and small fences, particularly those without dense vegetation, ensuring the safety and containment of your animals.
Equipped with intelligent battery management, the Sun Power S 250 offers extended autonomy, capable of operating for up to two weeks without direct sunlight. It also features deep discharge protection, indicated by a red flashing light when battery voltage drops below 11.2 V, safeguarding the battery's lifespan.

Setup
Proper setup is crucial for the optimal performance of your AKO Sun Power S 250. Follow these steps to ensure effective operation:
- Placement: Choose a location for the energizer that receives maximum direct sunlight throughout the day. Avoid shaded areas from trees, buildings, or dense vegetation. The solar panel should face south (in the Northern Hemisphere) for best results.
- Mounting: The energizer can be mounted on a fence post or a dedicated stand. Ensure it is securely fastened to prevent movement or damage from wind or animals.
- Grounding: Connect the energizer's ground terminal (usually marked with a ground symbol or "EARTH") to a suitable ground rod. The ground rod should be driven deep into moist soil, away from other electrical grounds. A good ground system is essential for effective fence performance.
- Fence Connection: Connect the energizer's fence terminal (usually marked with a lightning bolt or "FENCE") to your electric fence line. Use insulated wire designed for electric fences to prevent energy loss.
- Battery Connection: Ensure the internal 12V battery is properly connected. The intelligent battery management system will optimize charging from the solar panel.

Operating Instructions
Once properly set up, the AKO Sun Power S 250 operates largely autonomously. Here are key operational aspects:
- Power On/Off: Locate the power switch on the unit (refer to Figure 4 for typical switch location). Switch it to the "ON" position to activate the energizer.
- Intelligent Battery Management: The device features an intelligent battery management system that optimizes charging from the solar panel and manages power consumption. This ensures long operational periods, even during cloudy weather.
- Deep Discharge Protection: To protect the battery from damage, the energizer will enter a deep discharge protection mode if the battery voltage drops below 11.2 V. In this mode, a red light will flash, indicating low battery. The energizer will cease to output pulses until sufficient charge is restored.
- Seasonal Use: This energizer is designed for reliable, maintenance-free operation during the main grazing season. Its robust design ensures performance in various weather conditions.

Maintenance
Regular maintenance ensures the longevity and efficiency of your solar fence energizer:
- Solar Panel Cleaning: Periodically clean the surface of the solar panel with a soft, damp cloth to remove dust, dirt, or debris. A clean panel ensures maximum solar energy absorption.
- Vegetation Control: Keep vegetation clear around the fence line and the energizer. Overgrown plants can short out the fence and reduce energizer effectiveness.
- Connection Checks: Regularly inspect all connections (fence, ground, battery) to ensure they are secure and free from corrosion. Loose or corroded connections can lead to power loss.
- Battery Health: While the unit has deep discharge protection, it's good practice to monitor the battery indicator, especially during prolonged periods of low sunlight. If storing the unit for an extended period, ensure the battery is fully charged and disconnect it if possible, or store in a cool, dry place.
